BCC – Basal Cell Carcinoma

The most common type of skin cancer BCC or Basal Cell Carcinoma, originates on the outer most layer of the skin and usually appears in the most sun exposed areas. These lesions often present as open sores, red patches or crusty areas. BCC’s rarely spread, but if left untreated can grow larger and deeper.

SCC – Squamous Cell Carcinoma

This type of skin cancer affects hundreds of thousands Americans each year. It is usually located on areas exposed to the sun, such as face, hands and lower legs. SCC appears as red scaly spots or crusty open sores. If allowed to grow, these lesions penetrate deeper and may spread.

AK – Actinic Keratosis

Actinic Keratosis are precancerous skin lesions that may become squamous cell skin cancers if left untreated. These lesions are quite common and appear as dry, scaly or rough spots on the skin. They form on the sun exposed areas such as face hands and arms. AK’s are treated with cryosurgery, laser or prescription creams.

MM – Malignant Melanoma

It is the most dangerous form of skin cancer. This cancerous growth may appear as black, brown, red or even grey spot. Melanoma may develop on normal skin or within an already existing mole. If left untreated it can spread to other parts of the body and become difficult to treat. All new or changing moles that become larger, irregular, change in shape or color should be evaluated without delay.
